My doc wanted to make sure my hcg was going up so I went today (12/31) a week since the second one and it was 15,150. I guess I might be having twins, I'm having my first ultrasound on 1/11. This is my second ivf so I hope this one stays. I wish everyone a HAPPY NEW YEAR and SSBD, hopefully you will all get BFP in 2008. Hang in there and don't give up.
